Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current health data management systems face challenges in automating compliance with varying regulatory standards, leading to high costs, errors, and limited data interoperability and value due to the lack of inherent security and access controls.
Innovation Solution
A blockchain-based distributed ledger system with public key cryptography and separate storage of identity and digital transaction content, using cryptographic keys for fine-tuned access permissions, ensures compliance and data integrity across different use cases.

1Extent of automation
If traditional health data management systems are used, then data storage and access are possible, but compliance automation is difficult and costly with high human error
Solution Approach 1:
The blockchain system enables self-service compliance through smart contracts that automatically execute regulatory requirements. The system self-verifies data access requests against stored policies, automatically grants or denies access without human intervention, and maintains its own audit trails. This eliminates manual compliance checking and reduces human error while maintaining high reliability.
Solution Approach 2:
The system implements continuous feedback mechanisms where every data access transaction is recorded on the blockchain, creating an immutable audit trail. The system automatically monitors access patterns, compares them against compliance policies, and provides real-time feedback on compliance status. This enables automated compliance verification and reduces errors through continuous validation.
2Reliability
If manual compliance control processes are imposed on data systems, then regulatory requirements can be met, but system complexity and costs increase
Solution Approach 1:
The patent merges compliance control logic directly into the blockchain architecture itself, rather than adding separate manual control layers. The distributed ledger inherently provides audit trails, access control through cryptographic keys, and data integrity through consensus mechanisms. This integration eliminates the need for complex external compliance systems while maintaining regulatory adherence.
Solution Approach 2:
The blockchain-based system provides multiple compliance functions simultaneously: data integrity verification, access control, audit trail maintenance, and regulatory policy enforcement. The same blockchain infrastructure handles all these functions, reducing overall system complexity compared to having separate specialized systems for each compliance requirement.
3Reliability
If data is stored with inherent security controls, then data security and privacy are improved, but data interoperability and exchange value are limited
Solution Approach 1:
The system implements local quality through selective data disclosure using zero-knowledge proofs and encrypted data with fine-grained access control. Each data request is evaluated against stored policies, and only the minimum necessary information is revealed to the requester. This maintains strong data security at the local level while enabling controlled interoperability where authorized. The blockchain provides a shared reference framework that different systems can query without accessing underlying sensitive data.

AI summary
The present disclosure generally relates to methods, systems, apparatuses, and non-transitory computer readable media for managing health data. A method includes receiving a first data packet associated with a first user. The first data packet is assigned a universally unique identifier based on the first user. The method also includes causing an encryption of the first data packet. The method further includes storing at least one of the plurality of encryption keys on a first distributed ledger subnet. The method still further includes receiving the at least one of the plurality of encryption keys for the encrypted first data packet stored on the first distributed ledger subnet. The method also includes causing a decryption of the first data packet based on the at least one of the plurality of encryption keys for the encrypted first data packet stored on the first distributed ledger subnet.
